Currently the srt4 is the fastest car under 20 grand. They need a car thatll be cheaper and faster. They need to go for simplicity, simplicity is key to a successful sports car. Look at the Cobras they were small light powerful and simple cars, and they pretty much won any race they entered.
What would they call the car if they built a new 3 liter or 2.8 liter motor? Would it be 280z,300z,or 350z, odds are theyd keep the current 3.5 l and just call it the new 350z. But what do I know?
